Plain Bearings
Plain bearings are designed to support and guide rotating or sliding components through direct contact surfaces. By relying on a lubrication layer or self-lubricating materials, they provide smooth, stable operation with low noise and high load-carrying capacity. Their simple structure and ability to perform reliably under heavy loads and challenging conditions make them suitable for a wide range of applications

Classification of Plain Bearings
Spherical Plain Bearings
Spherical plain bearings can carry high-capacity radial and axial loads within a compact design, thanks to their large contact area. They are ideal for static and oscillating applications, offering excellent load distribution, durability, and resistance to shock loads, ensuring reliable performance in demanding operating conditions.
Rod End Bearings
Rod ends consist of an eye-shaped head with an integral shank that forms a housing for a spherical plain bearing. They are typically used at the ends of hydraulic or pneumatic cylinders to connect components, allowing misalignment and oscillating motion while ensuring reliable load transfer and stable performance in dynamic applications.
Plain Bushings
Bushings are suitable for rotating, oscillating, and linear movements, offering reliable performance across various applications. Straight (cylindrical) bushings are designed to accommodate radial loads only, while flanged bushings can support both radial loads and axial loads in one direction, providing additional positioning capability and improved stability in operation.
Slide / Plain Linear Bearings
Linear plain bearings are designed to provide smooth, uniform motion without stick-slip, while maintaining the same dimensions as corresponding linear ball bearings. Plastic variants offer self-lubricating performance under normal conditions, while aluminium outer rings provide excellent emergency running properties, ensuring reliable operation and durability across applications.
Advantages and Features
- High load-carrying capacity: Suitable for heavy loads and shock conditions.
- Low noise operation: Provides smooth and quiet performance without rolling elements.
- Simple and compact design: Requires less space and simplifies system structure.
- Excellent damping properties: Absorbs vibration and reduces impact.
- Good performance at low speeds: Ideal for oscillating and slow-speed applications.
- Low maintenance requirements: Self-lubricating options reduce the need for frequent servicing.
Applications
Plain bearings are designed for reliable performance under heavy loads and low-speed conditions. Their simple structure, low noise, and excellent damping properties help improve stability, reduce vibration, and extend service life. Here are typical application examples of plain bearings:
- Gearboxes
- Industrial machinery
- Transmission systems
- Automotive
- Wind energy equipment
- Metallurgical equipment
- Rolling mills
- Pumps and fans
- Compressors
- Turbines and power systems
